It is a well-known fact that the US does not want anything to do with Huawei’s tech especially when it relatest t0 5G. In fact, it has put consistent pressure on its allies to also shut Huawei out of their 5G construction. However, Huawei’s 5G remains the best bet for many nations thus its quite difficult to follow the US instruction. According to recent reports, despite pressure from the US, Hungary will still allow Huawei to participate in its 5G construction.
According to Peter Szijjarto, Hungarian Foreign Minister, the country will allow Huawei to participate in the construction of 5G networks. He made this statement at an event in China on Tuesday. Hijato pointed out that Huawei will build a Hungarian 5G network with Vodafone and Deutsche Telekom.
This means that Hungary did not heed the US “suggestions”, which indicates that Hungary did not see any evidence that Huawei’s equipment poses a security threat. According to the US, Huawei’s equipment comes with a “back door” that allows China to monitor other countries. Of course, Huawei denied these allegations.
Nevertheless, recent reports claim that Huawei and the US will soon be back in business. According to the US Secretary of Commerce, Wilbur Ross, Licenses for the sale of components to Huawei Technologies Co. will be available to US companies “soon”


Distribution¶
For the modeller, distribution of models is as simple as providing a model (either atomic or coupled) with the location where it should run and afterwards running it as a distributed simulation (as mentioned in How to run PyPDEVS).
Note
Since version 2.1, model distribution was simplified and a lot of restrictions on the model were dropped. Every model that was valid in local simulation, should now also be valid in distributed simulation.
Distributing the queue¶
Let’s extend the CQueue example from previous sections and add some distribution to it. Of course, this model only has two atomic models, which is clearly not an ideal model to distribute. Therefore, we will add some Queue atomic models in parallel, all taking the output from the single generator. Our model should look something like:
We will start of with implementing this model locally. This implementation is simple and shouldn’t be more difficult than the model in Examples for Parallel DEVS. It should look something like:
class DQueue(CoupledDEVS):
def __init__(self):
CoupledDEVS.__init__(self, "DQueue")
self.generator = self.addSubModel(Generator())
self.queue1 = self.addSubModel(Queue())
self.queue2 = self.addSubModel(Queue())
self.connectPorts(self.generator.outport, self.queue1.inport)
self.connectPorts(self.generator.outport, self.queue2.inport)
Note
Our original Queue atomic model was not written with multiple instances in mind. Therefore, the model name will not be unique in this simulation. In later versions of PyPDEVS, this doesn’t pose a problem apart from possibly confusing trace output.
Now all that is left is performing the actual distribution. Suppose we run 3 different nodes, with every atomic model on a seperate node. Thus the Generator runs on node 0, the first Queue runs on node 1 and the final Queue runs on node 2. This is as simple as altering the addSubModel method calls and add the desired node of the model being added. This results in:
class DQueue(CoupledDEVS):
def __init__(self):
CoupledDEVS.__init__(self, "DQueue")
self.generator = self.addSubModel(Generator(), 0)
self.queue1 = self.addSubModel(Queue(), 1)
self.queue2 = self.addSubModel(Queue(), 2)
self.connectPorts(self.generator.outport, self.queue1.inport)
self.connectPorts(self.generator.outport, self.queue2.inport)
Setting the location of a model, will automatically set the location of all its submodels with an unspecified location to the same location.
Note
Models for location 0 do not necessarily need to be specified, as the default is node 0. Leaving this option open (or specifying the location as None) means that it should take the location of the parent.
Additional options¶
A Simulator object that is initialized with a distributed model has several extra options that can be configured.
More advanced options are elaborated further on in their own Advanced examples subsection.
| setTerminationModel(model) | Marks model as being used in termination condition |
| registerState(variable, model) | Register a state to be fetched after simulation |
| setFetchAllAfterSimulation(fetch) | Completely update the model after simulation |
| setGVTInterval(gvt_int) | Calculate the GVT after every gvt_int seconds |
| setCheckpointing(name, chk_int) | Create a checkpoint after every chk_int GVT creation |
| setStateSaving(state_saving) | Change the method for state saving to state_saving |
Note
If any of these options are set during a local simulation, they will either throw a Exception or will simply have no effect.
Automatic allocation¶
Some models are very simple, but tedious, to distribute. As long as the actual allocation has no real importance, there is an additional option setAutoAllocation(autoAllocate) which will have the simulator distribute the models automatically. This distribution is rather efficient, though it is often suboptimal. It will simply try to balance the amount of atomic models at every node, not taking into account the actual activity of these models. Furthermore, it only works at the root level.
Even though it doesn’t perform intelligent distribution, it will work in situations where root models can work in parallel without influencing each other. More information can be found in Static Allocators
General tips¶
The distributed simulation algorithm that is being used is Time Warp. This means that every node will simulate optimistically in the assumption that other models have progressed as far as itself. As soon as a message from the past arrives, simulation at that node will be rolled back. This implies that nodes should have an equal load and that as few as messages should be exchanged between different nodes.
Therefore, the following rules should be taken into account to maximize the performance in distributed simulation:
- Models that exchange lots of messages should be on the same node
- Balance the load between nodes, so that the deviation is minimal
- Use homogeneous nodes
- Use quantums where possible, thus reducing the amount of messages
Note
Due to time warp’s property of saving (nearly) everything, it is possible to quickly run out of memory. It is therefore adviced to set the GVT calculation time to a reasonable number. Running the GVT algorithm frequently yields slightly worse performance, though it will clean up a lot of memory.

--- layout: archive title: Zulip Chat Archive permalink: /stream/113488-general/topic/Tactic.20help.html ---
Hi, in order to get familiar with writing tactics, I am trying to write a simple tactic to count the number of occurrences of ∅
in a goal. Here is what I have so far:
meta def is_empty' : expr → bool | `(has_emptyc.emptyc _) := tt | _ := ff meta def list_emptys' (e : expr) : list expr := e.fold [] (λ e' _ es, if (is_empty' e') then insert e' es else es) meta def find_empty : tactic unit := do e ← tactic.target, tactic.trace $ (list_emptys' e)
But if I run this tactic
universe u example {s : Type u} (a b : set s) : ∅ ∩ ∅ = a := begin find_empty, end
I only get [∅]
. Can someone help me figure out what I am doing wrong? I'm guessing it's me not understanding how fold
works for expr
...
you used insert
to accumulate the list, this removes duplicates
and the only thing you ever put in the list is ∅
(twice)
use ::
instead
Aha! that worked. Thanks @Mario Carneiro
anticlimax...
@Koundinya Vajjha Have you seen https://github.com/leanprover/mathlib/blob/master/docs/extras/tactic_writing.md? I have no idea about your level of experience with Lean or other programming languages. But for mathematicians who have never written anything in a functional programming language before, I think this is a very good introduction.

Hi All,
I'm a newbie but making progress here. I have an emonBase purchased in October and numerous emonTx's and emonTH's. A week ago some additional emonTH's and emonTx's came in.
I recently followed the directions here (http://openenergymonitor.org/emon/modules/emonpi#update) in order to use the web UI to update firmware in order to support recently purchased extra emonTx's and emonTH's. (It's now not clear to me that that was actually needed, but that's a tangent for another day.) That ran in to trouble with avrdude according to the logs. Eventually I tracked that down. It is apparently expected that in many cases one edit /home/pi/emonpi/emonpiupdate to comment out a few lines and uncomment other lines. I've done that and the update did seem to take. Thanks to all the answers in the forums that helped me figure that out.
Question:
I see that the update scripts run
git pull
commands. That doesn't seem compatible with expecting simple config changes like I just made. It seems like it would risk git pull overwriting config changes or having config changes block important git pull updates depending on how one handles this. This would seem to be particularly troublesome when one is requesting the update from the web UI where many of the details of the git pull commands will not be apparent.
What is our recommended way to minimize the config overwrite vs blocked update concern?
Re: git pull overwrites config changes?
I think I've read that there's a tentative plan to update this particular part of the code to parse out the emonhub.conf file and then appropriately take the right action. I assume the challenge here is that this code is bash and it's not particularly easy to parse an emonhub.conf formatted file from bash.
If this is the challenge, I'll offer to write a script to copy the emonhub.conf script in to a form that is is more easily parsed by bash. Perhaps something like the Java .properties file format? If I were to do this, what language would we want this code to be written in? PHP ?
Re: git pull overwrites config changes?
I'm not entirely clear what it is exactly you are proposing, nor am I sure how T&G would prefer to tackle the conf files.
Ideally the git update routine should not overwrite a couple of specific files eg emonhub.conf and settings.php, IMO it's a dangerous game to start parsing emonhub.conf, that may seem the best way to edit/add entries but it assumes alot. users may already be using settings that clash with the new stuff. If there are any duplicated node ids for example the conf simply will not load, if someone has edited their sketches payloads and an update alters the payload it could corrupt their data.
It is a much better approach to explain the changes and how to add them manually for a controlled manouver or there will need to be alternative documentation on how to determine the issue, fix and correct data for a multitude of possible issues.
The firmware update script should be made to A) know what hardware is connected and B) check what firmware for that device is being used, (this should remove any need for hard-coded options). Both of these can be determined from the emonhub.conf if that data is reliable and not over-written. The update script could also remind the user manual changes are required OR if done in the right manner, the updater should be able to update the emonhub.conf directly if it were a python script rather than bash, this would also make it cross-platform and usable on all nodes with the use of a programmer lead.
The emonhub.conf format is defined by the python "configobj" module, using bash is a quick and dirty fix with limited scope. I have some concerns for 3rd parties editing the emonhub.conf directly as is can cause emonhub to fail. but I am interested in what you had in mind.

public interface Relation
Simple relations, i.e. having only roles, no properties or methods, can be created directly by the Relation Service (represented as RelationSupport objects, internally handled by the Relation Service).
If the user wants to represent more complex relations, involving properties and/or methods, he has to provide his own class implementing the Relation interface. This can be achieved either by inheriting from RelationSupport class, or by implementing the interface (fully or delegation to a RelationSupport object member).
Specifying such user relation class is to introduce properties and/or methods. Those have to be exposed for remote management. So this means that any user relation class must be a MBean class.

We are pleased to announce that the Laboratory for Data Intensive Biology at UC Davis has joined the Software Carpentry Foundation as an Affiliate Member for three years starting in 2015. "We've been long-term supporters of Software Carpentry, and Affiliate status lets us support the Software Carpentry Foundation in a tangible way," said Dr. C. Titus Brown, the lab director. "This status also gives us the opportunity to include Software Carpentry as part of a larger biological data science training program at UC Davis."
Software Carpentry is a volunteer organisation whose goal is to make scientists more productive, and their work more reliable, by teaching them basic computing skills. Founded in 1998, it runs short, intensive workshops that cover program design, version control, testing, and task automation. In October 2014, a non-profit Software Carpentry Foundation was created to act as a governing body for the project. Affiliate status with the SCF provides preferential access to instructor training as well as waiving per-workshop fees.
The Laboratory for Data Intensive Biology (DIB) started in January 2015 with Dr. Brown's move to UC Davis. The lab is in the Department of Population Health and Reproduction in the School of Veterinary Medicine, and is part of both the Data Science Initiative and the Genome Center at UC Davis. DIB does fundamental and applied research on making use of the increasing volume and variety of biological data, and Dr. Brown currently has funding from the NIH and the Moore Foundation.
For more information, please see this announcement by Dr. Brown.

Crowchild is the code name for a game I began making using my custom-built “Apex Engine”. It is my first 2D game engine written using C++. It supports some basic game functionality and utilizes Box2D for physics and SFML for window creation and input management. School got in the way of me continuing this project further, and then I began working on a new 3D engine once I had some free time again.
You can find project’s source on my GitHub here: github.com/ajweeks/ApexEngine
(But I don’t recommend using it as a guide since it was my first personal engine)

Findings on the subject
I provided the second storyboard which was I originally developed to help structure what information I would share from the surplus research data as I converted to information, it helped me focus what was looking for having such a board subject structure, Still I presented it to the group and it was used as a main story board of the documentary not the final one as mine still was incomplete in a realistic sense given the assignment parameters.“They may produce original program ideas for consideration by producers, broadcasters, production companies, or other decision makers. They identify relevant data, contributors, locations or archive material etc. collate and assess information from various sources, and ensure that legal, compliance and copyright requirements are met.”Media-match, 2014
History and context
Identifying and covering a wide spectrum of thoughts processes that can occur for our actor’s character. Helped a lot in my research getting into the mind of what a student would look for if considering a vegan/vegetarian diet this also helped because myself as a vegan.
Finding interviewee’s was quite complex having so many suitable candidates “Research and preparation are the key to an effective interview. By the time you sit down to do the interview, you should know as much-or even more-about the topic than he interviewiee.”mollison,2010,Florence onus producer With this in mind finding potential candidates I narrowed it down to three, unfortunately one was unavailable logistical reasons resulted in us calling off arrangement.

“Before the day of the shoot, everyone should be given, in writing, call sheet” I provided details by email, speech and WhatsApp to all members of the group at least three day prior to interviews.
“…a list of key questions or topics. The director, researcher and host should have a preproduction meeting in which they discuss the questions/topics ahead of time and decide the order in which they will be addressed” 2010, producing videos we had pre talks before shooting on the day. Telephones email with myself and the interviewee’s questions were asked based on findings and our documentary’s scenario directions we raised to give the interviewee’s a understanding of what is expected of them and what they’d like to add as they were very open willing to give of themselves completely. For example we began with Alex Connell planning to have 6 meals however reasoning lead us to make the interview to what we considered to be more pertinent by producing footage for breakfast lunch and dinner.
The context was narrowed by sharing information that could be used for thoughts on the V-log and interview questions to guide the direction, which if needed I could supply more in-depth if required by the director. Information on teeth to add context, suffice of why conditions for someone would consider becoming vegan when cognitive making life style decision.

Perhaps the cause is a culmination of twenty something stressors—the kind that come with 70-hour workweeks and late nights on the pub circuit. But it's not just your mind that pays the price. A busy, high-stress lifestyle often leads to a diet of convenience—one that's lacking in vitamins and minerals, and overloaded with sugar, fat, and calories. The result: a body that never realizes its full potential.

Are you thinking about learning programming but not sure where to start? Take this quiz to find out which laguages might be best for you!
Front-end web development is the practice of converting data to graphical interface for user to view and interact with data through digital interaction using HTML, CSS and Javascript.
C# is most popular among bigger established businesses, often for building internal software. Because it's been around for a long time and has the backing of Microsoft, it is one of the most in-demand languages in the job market. C# has also been going through a bit of a rebirth lately, with Microsoft open sourcing the language and surrounding platform, porting it to run on Mac and Linux, and incorporating many of the best features of other languages. If you like the idea of working for a larger company on business software, C# is a great choice.
Java a favorite of enterprise companies, but its appeal is broader as well: it's one of the most popular of all programming languages, and it's used in everything from for high-performance processing to building Android user interfaces. Because Java has been very popular for a very long time and is used in so many applications, it is also a very high-demand language. If you're interested in working for an enterprise-level company, as an Android developer, or in high-performance applications, Java could be a good language to learn.
PHP is by far the most popular backend language today, with 80 percent of websites utilizing it 'server-side'. It is perhaps best known for it's use in content management systems like Wordpress, Drupal, and Joomla. But the versatility of the language and the frameworks it powers make employment options numerous and diverse. If you're keen to work for a fast paced agency that builds websites for lots of clients, or maintain the security and stability of a huge complex of government websites, or if you like the idea of building out small sites for brands, businesses, and organizations - In any of these cases, PHP would be a great way to go.
Ruby is a favorite language of developers building interactive web applications. If an app involves users creating accounts, entering information, and interacting with dynamic content, there's a good chance it is built with Ruby. Ruby became popular because the Rails framework, which is written with Ruby, simplified many of the common tasks associated with building web applications. It's most popular with startups and smaller companies who are looking to build their product quickly.

Overview
SQL2011 introduced temporal extensions to SQL
including AS OF SYSTEM TIME
and VERSIONS BETWEEN SYSTEM TIME
.
Ebean has support for this extension to SQL. The support for this falls into 2 general cases where some databases have SQL2011 support built in (Oracle, DB2, MS SQL Server 2016) or where it is not built in (Postgres, MySql) and Ebean generates history tables/triggers/views to support the feature.
Current support in Ebean
Oracle
via Total recallPostgres
via Triggers/history tableMySql
via Triggers/history tableH2
via Triggers/history table
History tables
For Postgres, MySql and H2 (and in general databases that don't have SQL2011 support built in) Ebean generates DDL for History tables and associated triggers and views. This is a common "Temporal database design" approach that has been used for some time and not specific to Ebean. For example, this approach is already implemented as a Postgres extension - arkhipov/temporal_tables.
In general the history table approach results in:
- A "history" table created that has the same (or very similar) structure as the "base table"
- The "history" table does not have constraints by default (no primary key, foreign key or indexes)
- 2 extra columns added to the base table and history table for "effective start" and "effective end" timestamp range. Postgres has a timestamp range type so that is preferred to 2 separate columns for the Postgres implementation. Note another approach uses 4 extra columns instead of 2 but we are not doing that.
- A view is used to
union all
combine the "base table" and the "history table" to simplify history queries - Triggers are used on update and delete to copy the existing row data from the "base table" to the associated "history table"
- Schema changes to the "base table" (add column etc) result in mirrored changes to the "history table" and potentially updates to the associated triggers

Compared to Change Log
Transactional
With @History changes are transactional and have the associated guarantees - changes can't be missed or lost.
Not bypassed
With @History the database handles all changes. If other frameworks (not Ebean) or stored procedures or raw JDBC is used to update the database all these changes are captured by the database triggers. Although Ebean makes it easier to query and generate the appropriate DDL the capturing of changes is a database function and not strictly tied to Ebean or the application.
Easy to query
With @History it is easy to query and view the data "As of" a given timestamp and view the versions and historic changes for a given bean/row. This is also possible with Change log but requires more work (loading the change log into say ElasticSearch and creating appropriate queries to return as of and version type data).
DB Overhead
A downside to @History relative to using Change log is that it does introduce extra costs to the database in terms of storage (history tables taking storage space) and in terms of impact to response time as updates and deletes now also copy data into the history tables.
The approach with Oracle Total Recall reduces the impact to response time by processing the copy of data from redo into the history tables in the background and in batch and that probably means it can generally be used more widely (on more base tables) than the traditional trigger based approach.
Schema changes
A downside to @History relative to using Change log is that schema changes (like adding a column) can mean more work / complexity as changes need to also be reflected in associated history tables and triggers. The DB migration support in Ebean mitigates this by generating all the appropriate changes to history tables and triggers etc.
@History
Add the @History
annotation to the entity beans that you want history support on. In the
case of Postgres and MySql this means that Ebean will generate DDL (triggers, views etc) to support
history on the underlying tables. For Oracle adding @History implies that the table has had flashback
archive already assigned to the table.
@HistoryExclude
Add the @HistoryExclude
annotation on entity bean properties that should be excluded from
history. This is expected to be used on large text or blob columns where there can be a relatively high
storage cost associated with keeping the history values and excluding these columns is desired.
ManyToMany intersection
In the case of intersection (bridge) tables for ManyToMany relationships by default the intersection
tables also have history. That is, if @History
is put on an entity bean then by default
the intersection tables for @ManyToMany
properties have history support (associated history
tables, views and triggers).
To exclude history from intersection tables @HistoryExclude
should be put on the @ManyToMany
property.
As of query
A Timestamp can be used with Query.asOf(Timestamp)
and Ebean will generate the query
such that the returning object graph represents the state as of the given timestamp. More accurately
for tables with history the query returns rows representing the table as of the given timestamp and for
other tables included in the query the rows returned represent 'current values'.
// asOf some time in the past like 1 hour ago, 1 week ago, 1 month ago etc
Timestamp asOf = ...;
Customer customer =
Customer.find.query()
.asOf(asOf)
.fetch("billingAddress")
.where().eq("name", "jim")
.findOne();
Scenario: Customer and Address both have history
In the above query if both Customer Address have history then both the customer data and address data will be returned 'As of' the given timestamp.
Scenario: Customer has history but Address does not
In the above query if Customer has history but Address does not then the customer data will be returned 'As of' the given timestamp but the address data will be returned using 'current data'.

That is, the AS OF
timestamp applies to the entire object graph loaded by and not just the
"origin query". If Address is lazy loaded and Address has history the address data will also be 'as of'
the original timestamp.
Versions between
Query.findVersionsBetween()
is used to return a list of versions for a given object
over time. The version beans returned contain a "diff" to the prior version as well as the
effective start and effective end timestamps.
Timestamp start = ...;
Timestamp end = ...;
List<Version<Customer>> customerVersions =
Customer.find.query()
.where()
.idEq(42)
.findVersionsBetween(start, end);
for (Version<Customer> customerVersion : customerVersions) {
Customer bean = customerVersion.getBean();
Map<String, ValuePair> diff = customerVersion.getDiff();
Timestamp effectiveStart = customerVersion.getStart();
Timestamp effectiveEnd = customerVersion.getEnd();
}
Who and When
It is generally expected that the entity beans should contain @WhoCreated
, @WhoModified
,
@WhenCreated
and @WhenModified
properties.
/**
* Common properties used by many entity beans.
*/
@MappedSuperclass
public class BaseModel {
@Id
Long id;
@Version
Long version;
@WhenCreated
Timestamp whenCreated;
@WhenModified
Timestamp whenModified;
@WhoCreated
String whoCreated;
@WhoModified
String whoModified;
...
@History
@Entity
@Table(name="customer")
public class Customer extends BaseModel {
@Size(max = 100)
String name;
...
Postgres
Postgres has an existing arkhipov/temporal_tables extension and Postgres/Ebean users could use this extension. By default Ebean does not use this extension but instead generates similar triggers. The difference between using arkhipov/temporal_tables or not comes down to DDL generation. Ultimately it would be good for Ebean to support DDL generation for arkhipov/temporal_tables but that isn't built into Ebean yet.
The other notable aspect of history support in Postgres is that we can make use of the timestamp range type with expected benefits in terms on indexing performance relative to using 2 separate timestamp columns.
MySql
There is a concern with MySql in the case where DDL changes need to be applied to a production database. In the case where Triggers need to change due to a schema change (like add column) MySql has no 'create or replace trigger' and instead a table lock needs to be held to drop and create the trigger. Holding a table lock in a production database might be a problem and restrict schema changes.
Oracle
Rob's View: Oracle Total recall has some nice advantages over the explicit trigger/history table approach. The main advantages being:
- Performance : low foreground cost - History table population occurs in the background and results in a much lower overhead/impact on foreground response time
- Performance : batch processing - History table population can be processed in batch reducing the overhead/impact for many small updates
- Admin : reduced DDL - Table alterations (add columns etc) are handled automatically reducing the admin costs of maintaining triggers/views/history tables.

RESPONSORIAL PSALM
Jonah 2:<IP_ADDRESS> (R. 6d)
R. You brought up my life from the pit, O Lord.
I called to the LORD, out of my distress, and he
answered me; out of the belly of Sheol I cried, and you heard my voice.
R. You brought up my life from the pit, O Lord.
For you cast me into the
deep, into the heart of the seas, and the flood was round about me; all your
waves and your billows passed over me.
R. You brought up my life from the pit, O Lord.
Then I said: I am cast out from your presence; How shall I again look upon your holy temple?
R. You brought up my life from the pit, O Lord.
When my soul fainted within me, I remembered the
LORD; and my prayer came to you, into your holy temple.
R. You brought up my life from the pit, O Lord.
FIRST READING Galatians 1:6-12
I did not receive the Gospel from man, nor was I taught it, but it came through a revelation of Christ.
A reading from the Letter of Saint Paul to the Galatians
Brethren: I am astonished that you are so quickly
deserting him who called you in the grace of Christ and turning to a different
gospel-- not that there is another gospel, but there are some who trouble you and
want to pervert the gospel of Christ. But even if we, or an angel from heaven,
should preach to you a gospel contrary to that which we preached to you, let
him be accursed. As we have said before, so now I say again, If
any one is preaching to you a gospel contrary to that which you received, let
him be accursed. Am I now seeking the favour of men, or of God? Or am I trying
to please men? If I were still pleasing men, I should not be a servant of
Christ. For I would have you know, brethren, that the gospel which was preached
by me is not man's gospel. For I did not receive it from man, nor was I taught
it, but it came through a revelation of Jesus Christ.
The word of the Lord
RESPONSORIAL PSALM Psalm 111:1b-2.7-8.9 and 10c (R. 5b)
R. The Lord keeps his covenant ever in mind.
I will praise the LORD with all my heart, in the
meeting of the just and the assembly. Great are the works of the LORD, to be
pondered by all who delight in them.
R. The Lord keeps his covenant ever in mind.
His handiwork is justice and truth; his precepts
are all of them sure, standing firm for ever and ever, wrought in uprightness
and truth.
R. The Lord keeps his covenant ever in mind.
He has sent redemption to his people, and
established his covenant for ever. Holy his name, to be
feared. His praise endures for ever!
R. The Lord keeps his covenant ever in mind.
R. Alleluia. A new commandment I give to you, says the Lord, that you love one another, even as I have loved you. R. Alleluia.
GOSPEL Luke 10:25-37
“Who is my neighbour?”
A reading from the holy Gospel according to Luke
At that time: Behold, a lawyer stood up to put
Jesus to the test, saying, "Teacher, what shall I do to inherit eternal
life?" He said to him, "What is written in the law? How do you
read?"  And he
said to him, "You have answered right; do this, and you will live."
But he, desiring to justify himself, said to Jesus, "And who is my
neighbour?" Jesus replied, "A man was going down from

QUILLS (Fox Searchlight) Starring: Geoffrey Rush, Kate Winslet, Joaquin Phoenix, Michael Caine. Screenplay: Doug Wright, based on his play. Producers: Julia Chasman, Peter Kaufman and Nick Wechsler. Director: Philip Kaufman.  Reviewed by Scott Renshaw.
As the title character in THE PEOPLE VS. LARRY FLYNT, Woody Harrelson says at one point (and I paraphrase), "If the First Amendment protects a scumbag like me, then it will protect anybody." That's the approximate thematic gist playwright Doug Wright is going for in QUILLS: an exploration of the idea that even free speech at its most extreme and offensive should still be free. It's a worthy enough idea to espouse, and the movie based on Wright's QUILLS should have been plenty worthy as well -- if only it weren't so damned self-congratulatory about its position. As splendidly staged as Philip Kaufman's cinematic version of QUILLS may be, it's ultimately stunted by a text so concerned with making its artistic points that it flops as simple story-telling.
QUILLS takes us to Paris during the reign of Napoleon, where street vendors are selling scandalous, sexually explicit novels attributed to "Anonymous." Of course, everyone knows they are the work of the Marquis de Sade (Geoffrey Rush), even though he is currently an inmate of Charenton Asylum under the kindly supervision of a priest, the Abbe Coulmier (Joaquin Phoenix). He has been smuggling out his work with the help of a laundress named Madeleine (Kate Winslet), arousing the ire of Napoleon himself. The emperor sends Dr. Royer-Collard (Michael Caine), noted alienist, to clean up matters at Charenton. But the not-so-good doctor finds that silencing de Sade will be no easy matter, as the prolific nobleman is practically compelled to spill his obscene thoughts onto paper.
Thus begins an all-around celebration of the purgative powers of porn. The Marquis, we are told, has been so tainted by the world around him that he must spill "the toxins in his head" into his stories; Madeleine, who revels in his naughty work, tells Coulmier, "If I wasn't such a bad woman on the page, I'll hazard I couldn't be such a good woman in life." QUILLS offers a dozen different defenses of free speech at its most unfettered, including commentary that we must know vice in order to appreciate virtue, and a taunt from the Marquis to the Abbe: "Are your convictions so fragile that they cannot stand in opposition to mine?" Every five minutes or so, there's another re-phrasing of the same point in a slightly different way: Art is just art, words are just words, and even the most ghastly art and the most ghastly words must be given their table in the marketplace of ideas.
A debatable point, to be certain, but the problem isn't so much whether or not one concurs with Wright's absolutist interpretation of freedom of speech.  Winslet and Phoenix are effective as the essentially good people aware of their darker impulses, but Wright is mostly interested in them as representations of the dark impulses in all of us. Michael Caine plays one narrow-eyed note as the hypocritical man of morality who, naturally, is sexually cruel to his own young wife (Amelia Warner) and leeches funds from de Sade's wife to help finish his opulent home. And Rush, while thoroughly entertaining as the ultimate libertine, never gets at what de Sade was ultimately all about as a human being. Once you've figured out what Wright is saying in QUILLS -- and it doesn't take all that long -- the playing out of the narrative feels like a long walk around in circles.
Wright does deserve credit for not taking the easiest ways out with his arguments. He shows de Sade's work provoking a group of madmen to violent acts, and he doesn't soft-pedal the cruel, petulant de Sade himself as a torture artist just to make him more sympathetic as a tortured artist. There are several individually enjoyable scenes in QUILLS, from the "telephone game" rendering of one of de Sade's tales to the staging of a bawdy play intended to humiliate Royer-Collard. Physically, it's a lovely production to behold. Emotionally, it is provocative stuff. But intellectually, it's redundant. It's clear that Wright believes even the kind of art that could inspire a Columbine massacre must not be suppressed. It's equally clear that he feels pretty good about himself for saying so. Ironically, QUILLS probably works best as simple, sensual, prurient-interest entertainment. As a presentation of ideas, it's more thesis than theater.
On the Renshaw scale of 0 to 10 ink tanks: 6.

FBI Draft Resolution Calls for End-to-End Encryption Ban
by Andrew OrrAn FBI draft resolution for Interpol calls for a ban on end-to-end encryption. It’s for Interpol’s 37th Meeting of the INTERPOL Specialists Group on Crimes Against Children.
A draft of the resolution viewed by Ars Technica stated that INTERPOL would “strongly urge providers of technology services to allow for lawful access to encrypted data enabled or facilitated by their systems” in the interest of fighting child sexual exploitation. Currently, it is not clear whether Interpol will ultimately issue a statement.
Remember when I mentioned the Four Horses of the Infocalypse? Terrorists, drug dealers, pedophiles, and organized crime. Four fears to use as a way to push their agenda. I know it’s a delicate issue. These groups are definitely ones that the majority of society would want to stop. But removing end-to-end encryption for everyone isn’t the way to do that.

Configure > HTTP/2 Directives
H2O provides one of the world's most sophisticated HTTP/2 protocol implementation, including following features.
Prioritization
H2O is one of the few servers that fully implement prioritization of HTTP responses conformant to what is defined in the HTTP/2 specification. The server implements a O(1) scheduler that determines which HTTP response should be sent to the client, per every 16KB chunk.
Unfortunately, some web browsers fail to specify response priorities that lead to best end-user experience. H2O is capable of detecting such web browsers, and if it does, uses server-driven prioritization; i.e. send responses with certain MIME-types before others.
It is possible to tune or turn off server-driven prioritization using directives: file.mime.addtypes
, http2-reprioritize-blocking-assets
.
See also:
Server push
H2O recognizes link
headers with preload keyword sent by a backend application server (reverse proxy or FastCGI) or an mruby handler, and pushes the designated resource to a client.
link: </assets/jquery.js>; rel=preload; as=script
When the HTTP/2 driver of H2O recognizes a link
response header with rel=preload
attribute set, and if all of the following conditions are met, the specified resource is pushed to the client.
- configuration directive http2-push-preload is not set to
OFF
- the
link
header does not have thenopush
attribute set - the
link
header is not part of a pushed response - the client does not disable HTTP/2 push
- number of the pushed responses in-flight is below the negotiated threshold
- authority of the resource specified is equivalent to the request that tried to trigger the push
- (for handlers that return the status code synchronously) the status code of the response to be pushed does not indicate an error (i.e. 4xx or 5xx)
The server also provides a mechanism to track the clients' cache state via cookies, and to push the resources specified with the link
header only when it does not exist within the clients' cache. For details, please refer to the documentation of http2-casper
configuration directive.
When a resource is pushed, the priority is determined using the priority
attribute of the MIME-type configuration. If the priority is set to highest
then the resource will be sent to the client before anything else; otherwise the resource will be sent to client after the main content, as per defined by the HTTP/2 specification.
HTTP/1.1 allows a server to send an informational response (see RFC 7230 section 6.2) before sending the final response. Starting from version 2.1, web applications can take advantage of the informational response to initiate HTTP/2 pushes before starting to process the request. The following example shows how such responses would look like.
HTTP/1.1 100 Continue
Link: </assets/style.css>; rel=preload; as=style
Link: </assets/jquery.js>; rel=preload; as=script
HTTP/1.1 200 OK
Content-Type: text/html; charset=utf-8
<!doctype html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="/assets/style.css">
<script type="text/javascript" src="/assets/jquery.js"></scrrpt>
...
Pushed responses will have x-http2-push: pushed
header set; by looking for the header, it is possible to determine if a resource has been pushed.
It is also possible to log the value in the access log by specifying %{x-http2-push}o
, push responses but cancelled by CASPER will have the value of the header logged as cancelled
.

Latency Optimization
When using HTTP/2, a client often issues high-priority requests (e.g. requests for CSS and JavaScript files that block the rendering) while a lower-priority response (e.g. HTML) is in flight. In such case, it is desirable for a server to switch to sending the response of the high-priority requests as soon as it observes the requests.
In order to do so, send buffer of the TCP/IP stack should be kept empty except for the packets in-flight, and size of the TLS records must be small enough to avoid head-of-line blocking. The downside is that obeying the requirement increases the interaction between the server process and kernel, which result in consumption of more CPU cycles and slightly increased latency.
Starting from version 2.1, H2O provides directives that lets the users tune how the TCP/IP stack is used depending on the observed RTT, CWND, and the additional latency imposed by the interaction between the server and the OS.
For TCP/IP connections with greater RTT and smaller CWND than the configured threshold, the server will try to keep the size of HTTP/2 frames unsent as small as possible so that it can switch to sending a higher-priority response. Benchmarks suggest that users can expect in average 1 RTT reduction when this optimization is enabled. For connections that do not meet the criteria, the server will utilize the TCP/IP stack in ordinary ways.
The default values of the thresholds have been chosen that the optimization will come into action for mobile and long-distance networks but not when a proxy exists on the network.
The optimization is supported only on Linux and OS X. The two are the operating systems that provide access to TCP_INFO
and an interface to adjust the size of the unsent buffer (TCP_NOTSENT_LOWAT
).
Please refer to the documentation of the directives below to configure the optimization:
http2-latency-optimization-min-rtt
http2-latency-optimization-max-additional-delay
http2-latency-optimization-max-cwnd

http2-graceful-shutdown-timeout
-
http2-allow-cross-origin-push
- Description:
-
Configures CASPer (cache-aware server-push).
When enabled, H2O maintains a fingerprint of the web browser cache, and cancels server-push suggested by the handlers if the client is known to be in possession of the content. The fingerprint is stored in a cookie named
h2o_casper
using Golomb-compressed sets (a compressed encoding of Bloom filter).If the value is
OFF
, the feature is disabled. Push requests (made by the handlers through the use ofLink: rel=preload
header) are processed regardless of whether if client already has the responses in its cache. If the value isON
, the feature is enabled with the defaults value specified below. If the value is mapping, the feature is enabled, recognizing the following attributes.- capacity-bits:
- number of bits used for the fingerprinting.
Roughly speaking, the number of bits should be
log2(1/P * number-of-assets-to-track)
where P being the probability of false positives. Default is13
, enough for tracking about 100 asset files with 1/100 chance of false positives (i.e.log2(100 * 100) =~ 13
). - tracking-types:
- specifies the types of the content tracked by casper.
If omitted or set to
blocking-assets
, maintains fingerprint (and cancels server push) for resources with mime-type ofhighest
priority. If set toall
, tracks all responses.
log2(P) * number-of-assets-being-tracked
bits multiplied by the overhead of Base 64 encoding (4/3
). Therefore with current cookie-based implementation, it is necessary in many cases to restrict the resources being tracked to those have significant effect to user-perceived response time.http2-casper: ON # `ON` is equivalent to: # http2-casper: # capacity-bits: 13 # tracking-types: blocking-assets

- Default:
http2-casper: OFF

file.mime.addtypes
, issue #421
- Description:
-
A directive to turn on the HTTP/2 Implementation Debug State.
This experimental feature serves a JSON document at the fixed path
/.well-known/h2/state
, which describes an internal HTTP/2 state of the H2O server. To know the details about the response fields, please see the spec. This feature is only for developing and debugging use, so it's highly recommended that you disable this setting in the production environment.The value of this directive specifies the property set contained in the response. Available values are
minimum
orhpack
. Ifhpack
is specified, the response will contain the internal hpack state of the same connection. Ifminimum
is specified, the response doesn't contain the internal hpack state.In some circumstances, there may be a risk of information leakage on providing an internal hpack state. For example, the case that some proxies exist between the client and the server, and they share the connections among the clients. Therefore, you should specify
hpack
only when the server runs in the environments you can completely control.This feature is considered experimental yet. For now, the implementation conforms to the version draft-01 of the specification.

"http2-latency-optimization-min-rtt"
- Description:
-
Minimum RTT (in milliseconds) to enable latency optimization.
Latency optimization is disabled for TCP connections with smaller RTT (round-trip time) than the specified value. Otherwise, whether if the optimization is used depends on other parameters.
Setting this value to<PHONE_NUMBER> (i.e.
UINT_MAX
) effectively disables the optimization. - Level:
- global
- Default:
http2-latency-optimization-min-rtt: 50
- Description:
-
Maximum additional delay (as the ratio to RTT) permitted to get latency optimization activated.
Latency optimization is disabled if the additional delay imposed by the interaction between the OS and the TCP/IP stack is estimated to be greater than the given threshold. Otherwise, whether if the optimization is used depends on other parameters.
- Level:
- global
- Default:
http2-latency-optimization-max-additional-delay: 0.1
"http2-latency-optimization-max-cwnd"
- Description:
-
Maximum size (in octets) of CWND to get latency optimization activated.
CWND is a per-TCP-connection variable that represents the number of bytes that can be sent within 1 RTT.
The server will not use or stop using latency optimization mode if CWND becomes greater than the configured value. In such case, average size of HTTP/2 frames buffered unsent will be slightly above the
tcp_notsent_lowat
sysctl value. - Level:
- global
- Default:
http2-latency-optimization-max-cwnd: 65535
"http2-push-preload"
- Description:
-
A boolean flag (
ON
orOFF
) indicating whether if the server should push resources when observing alink: rel=preload
header. - Level:
- global, host
- Default:
http2-push-preload: ON
- Description:
-
A boolean flag (
ON
orOFF
) indicating if the server should send contents withhighest
priority before anything else.To maximize the user-perceived responsiveness of a web page, it is essential for the web server to send blocking assets (i.e. CSS and JavaScript files in
<HEAD>
) before any other files such as images. HTTP/2 provides a way for web browsers to specify such priorities to the web server. However, as of Sep. 2015, no major web browsers except Mozilla Firefox take advantage of the feature.This option, when enabled, works as a workaround for such web browsers, thereby improving experience of users using the web browsers.
Technically speaking, it does the following:
- if the client uses dependency-based prioritization, do not reprioritize
- if the client does not use dependency-based prioritization, send the contents of which their types are given
highest
priority before any other responses
- Level:
- global
- Default:
http2-reprioritize-blocking-assets: ON
- See also:

Referendum: 10 reasons why NDC says Ghanaians must vote ‘NO’
The Communications Bureau of the National Democratic Congress (NDC) has offered what it says are 10 reasons why voters at the December 17 referendum to amend the 1992 constitution to allow political parties sponsor candidates to local level elections must vote NO and reject the proposal.
The list of 10 reasons pointing out the benefits of a NO vote as well as the ills and ramifications if the constitution is amended to accommodate the proposal, cites among other things, the ‘needless political divisiveness and rancor’ and the avoidance of “an expensive and exclusionary political primaries system”.
Below is the statement issued by the NDC
ON THE IMPENDING DECEMBER 17TH REFERENDUM
WHAT YOU NEED TO KNOW
* The December 17th Referendum is not about whether or not MMDCEs should be elected. Rather, it is about allowing political parties to sponsor candidates in unit committee, assembly member and MMDCE elections.
* Thus, simply put, A YES vote is for partisanship in our local government system and a NO vote is for a United Ghana at the local government level.
10 REASONS WHY EVERY GHANAIAN MUST VOTE NO
Vote NO to avoid the needless political divisiveness and rancor at the local level, and rather promote unity and cohesion at the local government level.
Vote NO to deepen stakeholder consultations and consensus-building for development at the local government level. This is what propels the development of local communities, not political grandstanding.
Vote NO for a less expensive and a less monetized election system at the local government level. Local politics must not be the preserve of the highest bidder and those with moneybags.
Vote NO to encourage competent Ghanaians who don’t want to be tagged with partisanship to participate in governance at the local level.
Vote NO to avoid the party whip system and protect the independence of Assembly and unit committee members in decision-making at the local government level.
Vote NO to ensure the continuity of developmental projects at the local government level in the supreme interest of the community. The phenomenon of abandoned projects will only get worse if a YES vote is entertained.
Vote NO to deepen accountability of Assembly and unit committee members as well as elected MMDCEs to the people at the local government level.
Vote NO to avoid an expensive and exclusionary political primaries system which will produce mainly the affluent, the educated etc. as assembly members and unit committee members.
Vote NO to avoid inimical partisan acrimony which sometimes prolongs even after elections, and ensure civility and decorum in local government elections.
Vote NO for community-interest decisions and not parochial partisan decisions at the local government level. Long before parties were formed, communities existed and governed themselves.
CONCLUSION: Enough of the extreme partisanship that ails Ghana’s development at the national level. VOTE NO TO PROTECT GHANA’S LOCAL GOVERNMENT SYSTEM FROM DESTRUCTION. Ghana first!
Thank you.
NCB-HQ, NDC
